nazi's breeding farm, anyone know this? what your opinion?

nazi's breeding farm is a place to nazi women give birth to produce "pure race" of aryan. the house contained of women who's selected by nazi as "ideal" women to produce "super baby". the women impregnated by nazi's officer who's "ideal" men as "pure aryan", and expected to produce "ideal aryan's generation" and fix their generation to a perfect generation for the future. The baby who are not in accordance with the criteria will be eliminated. I think this is like animal breeding, an unhuman behavior.
do you ever heard this story? there is any myloter from german or the german's neighbor country know this and want to share their story?
thanks...
